Convert ODS to PNM

An OpenDocument Spreadsheet (ODS) file is utilized for storing spreadsheet data and is compatible with various office software suites such as Apache OpenOffice Calc. Originating from the OASIS Open Document Format for Office Applications (ODF) standard, the ODS extension ensures interoperability across different software platforms by using XML-based open format. First ratified in 2005, ODF was developed to provide an open, vendor-neutral format for office applications, promoting accessibility and long-term archival. In a professional IT context, ODS files are valued for their flexibility, standardization, and ability to be integrated seamlessly into diverse computational environments.

The PNM (Portable Anymap) file extension, developed by Jef Poskanzer in the 1980s, stands for Portable Any Map. It is an uncompressed raster graphics format designed for portable image storage and exchange, encompassing three sub-formats: PBM (Portable Bitmap), PGM (Portable Graymap), and PPM (Portable Pixmap). PNM files store image data in plain text or binary format, ensuring easy usage across different platforms and applications. This format is widely supported by various image editing software and is valued for its simplicity and lossless compression.
